Record Features

RecordFeatures.scala

  //
  //  A class does not need any reference to the `Mapper`.
  //  Here it is defined as a case class because it's convenient - no need for new and
  //  the compiler generates equals, hashCode, copy and extractor methods - but
  //  it can be a normal class.
  //
  case class Person( first:String, last:String, age:Int )

  //
  //  A record does not need to be a class companion but it is convenient
  //    because the implicit conversion to `Record` is automatically in scope.
  //    ( see tests below )
  //
  object Person extends Mapper[Person] {

    def key = first

    val first = "first" is { _.first } // name is getter
    val last  = "last"  is { _.last  }
    val age   = "age"   is { _.age   }

    //Same order as the constructor
    def properties = first :: last :: age :: Nil

  }
